Report Style: AER
Reports azimuth, elevation, and range values for the relative position vector between the base object and the target object, during access intervals. The relative position includes the effects of light time delay and aberration as set by the computational settings of the access. Az-El values are computed with respect to the default AER frame of the selected object of the Access Tool, as described below.
Reference Frames in AER Reports
AER reports for accesses are based on a default local coordinate system for every type of STK object.
For facilities, places, and targets the local coordinate system is LH.
- Azimuth is referenced to X, positive towards Y (clockwise from above).
- Elevation is referenced to X-Y plane, positive along negative Z.
For aircraft, ships, and ground vehicles the local coordinate system is VVLH CBF (Central Body Fixed).
- Azimuth is referenced to X, positive towards Y (clockwise from above).
- Elevation is referenced to X-Y plane, positive along negative Z.
For satellites and missiles the local coordinate system is VVLH CBI (Central Body Inertial).
- Azimuth is referenced to X, positive towards Y.
- Elevation is referenced to X-Y plane, positive along negative Z.
For other objects, the local coordinate system is found using the object's parent (or grandparent) as applicable.
LH (Local Horizontal)
X axis = constrained toward local north
Y axis = local east
Z axis = aligned with local geodetic nadir
VVLH (Vehicle Velocity, Local Horizontal)
X axis = constrained toward velocity vector
Y axis = perpendicular to X and Z.
Z axis = aligned with geocentric nadir

Column Listing
| Column | Column Name | Element | Type | Dimension | Description |
|---|---|---|---|---|---|
| 1 | Time | Time | Real Number or Text | Date | Time. |
| 2 | Azimuth | Azimuth | Real Number or Text | Longitude | Angle measured from the X-axis of the direction of the relative position vector, positive about the axis used to measure positive elevation. |
| 3 | Elevation | Elevation | Real Number or Text | Angle | Angle measured from the XY-plane to the direction of the relative position vector. |
| 4 | Range | Range | Real Number | Distance | Magnitude of the relative position vector. The relative position vector reflects the access settings for light time delay, aberration, and refraction. |
